DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved structure of a traversing device for a winding material in a high-rigidity rod winding device.

[0002]

2. Description of the Related Art In a conventional bar winding device, as shown in FIG. 5, a winding material lateral feeding device 30 is provided in front of a winding drum 32. This take-up material lateral feeder 30 is composed of a pair of opposed vertical rolls 31, 31, and a single roll 31 is applied to the take-up material A between the take-up drum 32 and the rolls 34, 34 on the fixed roll 33. This allows the material A to be fed sideways to align and wind the winding material A on the winding drum 32. A 'indicates a state in which the winding material A has been wound.

[0003]

In the conventional apparatus described above, when traversing by the take-up material traversing device 30, as shown in FIG. 6, due to the rigidity of the take-up material, it is bent at a diameter larger than the diameter of the rotary roll 31. It is preferable to be in a state. However, in order to improve the winding state of the winding material A on the winding drum 32, as shown in FIG. The winding material A is bent 35.

As described above, when the rotating roll 31 is bent along the outer surface or is bent with a small bending radius, the reciprocal of the bending radius is proportional to the bending resistance. Will be. Further, continuous bending by the rotating roll 31 becomes unstable in a range where the rotating roll 31 does not adhere to the outer surface and the bending radius is small.

Conventionally, in order to prevent the above-described increase in bending resistance and instability of continuous bending, the distance between the rolled-up material traversing device 30 and the fixed roll 33 is increased so that the rolled-up material is traversed. In order to reduce the bending angle of the roll and to make the continuous bending unstable, a method of applying a large tension to the wound material so as to bend completely along the outer surface of the rotating roll 31 is adopted.

However, in this case, a large installation space is required for the entire equipment including the winding device, and the size of the equipment is increased.

Therefore, the present invention does not cause an increase in the bending resistance of the wound material during the transverse feed and instability of continuous bending of the wound material. The purpose of the present invention is to provide a take-up material traversing device for a bar take-up device that can save space by shortening the distance between them and can also achieve energy saving.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention is directed to a winding material traversing device for a bar winding device as follows. That is, in a bar winding device for winding a rod-shaped winding material on a winding drum, a plurality of vertical rotary rolls are provided at a position in front of the winding drum when laterally fed by an outer surface thereof. It is arranged so as to form an arc with a bending radius larger than the cross-sectional radius of the rotating roll on the winding material, and is provided so as to be connected to the traversing function section in a state where the tangential direction of the arc matches the winding direction of the winding material It is characterized by being obtained.

In the above-mentioned bar winding device according to the present invention, various types of bars such as iron, copper, and aluminum can be wound. Accordingly, the bending radius of the above-mentioned arc in the rolled material traversing device according to the present invention also differs according to the type of the rolled material to be processed. For example, when the rolled material is a copper material, the bending radius Can be arranged in an arc of about 10 m.

[0010] In the bar winding device according to the present invention, the fixed roll corresponding to the winding material traversing device may be configured so that the winding material does not bend with a small radius.
Conventional ones can be used as they are. In order to prevent the winding material from being bent at a small radius on the fixed roll side, various configurations such as a configuration in which rolls arranged in an arc shape similar to the winding material traversing device according to the present invention may be used. it can.

Further, the lateral feed function section can be constituted by, for example, a ball screw unit.

[0012]

According to the present invention, the following effects are obtained. The component constituted by the plurality of rotating rolls arranged at the arc position is located between the winding drum and the fixed roll in the bar winding device in accordance with the operation of the continuous traverse function unit. It comes into contact with the inner winding material.

At this time, a corresponding portion of the winding material is bent along an arc surface by each of the above-mentioned rotating rolls. However, since this bending is restricted to be equal to or larger than the bending radius of the arc, the winding material does not bend with a small radius. Therefore, even if the tension on the rolled material increases, the bending resistance of the rolled material portion is kept below a certain value, and the bending radius of the rolled material does not reach an unstable range, so that continuous bending can be stabilized. it can.

Further, since the tangential direction of the arc formed by each rotating roll coincides with the winding direction of the winding material, the laterally fed winding material is positioned at the winding position on the winding drum. And the wound material is sequentially wound in an aligned state on a winding drum.
